l f 'Application s ein This vinvention relates to panel 'cutting and`the like, being applicable to sawing up, trimming,- grooving, andotherwise cutting sheet material,

'andeslpecially to cutting sheets or panelsl with 5` rabbetedAorship--lap edges. We aimto do `this conveniently, rapidly,inexpensively and with the utmost-economy of material. The invention is`adaptable and advantageous "for insulation, buildingboard, homogeneoushardwood board;

" paperl'wood and fiber pulp board, and other IV, with certain partsinvertical section asiridi-` cated by the line andarrows V--V in Fig. IV:

sheet materials that can be saWed or cut with milling cutters orgrinding wheels. Various advantages that canbe realized through theinven-l tion will appear from our-description hereinafter. of'lafs'elected` and preferred embodiment, whichl isspeciallyuseful fortrimming the 'edges of ber boardsheets andA cutting them into parallel-`edgds't'rips, aswellas for bringing the edges `to ship-lap formation,`or cutting grooves 4in the sheetsorstrips` parallel with their edges.

i The machine here shown (Figs.

'-Bothplate`l'andV rollers 1j7`are1supported at a convenient height by suitable'Asubstructure or 'framing 18.1 Preferably,` the sheetmaterial S is`definitely controlledduring "the `action ofy the cutters `on it,` as bymeans of transversely extending rotary feed rolls 19jlocated close infront of and behind the cutters, so as-.to assurestraight cuts. `Asshown in Figs.

"Preferably, the ways 24` project through and beyondone or both of the side frames26, 26, to allow `cutters 15l to be setclear outto thelimitofthe width between these frames. As shown in FigsIand IVI-there are supports or presser feet 32 atopzii" 'is posite sidesof the sheet S from the cutters 15, to sustain the sheet against thethrust due to the cutters.

message `the cutters is associated a presser-foot or support 32. Therelations of the parts to one another and to the feed rolls 19 and thesheet S are shown in Fig. X. The saws 90 of the cutters 15 being atuniform intervals and at opposite sides of the sheet S in alternation,the strips are of uniform width and are oppositely rabbeted on theiredges. Fig. IUI shows how strips of ber board ship-lapped as in Figs.VIII and X are assembled in a plastered wall, nailed to studding 93, andcovered with plaster Figs. IX and XI illustrate the use of such amachine to make` board with edges bevelled as well as ship-lapped. Hereeach milling cutter 91a of the (edge-trimming and central) lower l uppercutters 15 are the same as in Figs. VIII and X; but their correspondingsupports 32a are double, with pairs of oppositely-facing conical-edgedmilling cutter discs 91h between,

` forming a double conical or (90) V-cutter 95.

Fig. IX shows the cutting alignment of coacting upper cutters 15 andthese extra lower cutters 95, and Fig. XI shows their axial relation: i.e., their axes are not directly opposite, but somewhat offset in thedirection of cut, so that they both cut to the median plane of the sheetS without any possibility of clashing. Accordingly, the edges of eachstrip produced are different: i. e., while rabbeted toward oppositesides, they are bevelled toward the same side. Fig. XIII shows how suchstrips of fiber board are assembled in use, nailed on studding 93, andplastered over at 95. The bevels of intertting edges coact to form (90)V-grooves 96 that help to hold the plaster 95.
